CodexSwitch v1.8.0

Added

• Added Claude Code as an alternative client for the existing provider, model
  and reasoning selection. Commander can now apply and launch either Codex or
  Claude with the same active configuration.
• Added an Anthropic Messages compatibility route to the unified provider
  proxy for Azure OpenAI, OpenCode Go, OpenRouter and an explicitly
  experimental native OpenAI Codex OAuth route.
• Added persistent, merge-safe Claude settings and an API-key helper that
  starts the loopback proxy on demand without storing provider credentials in
  Claude configuration.
• Added Microsoft Foundry as a Claude-only provider using Claude Code's native,
  proxy-free Foundry integration. It supports Entra ID, vault-backed API keys
  and custom deployment names without writing keys to Claude settings.
• Added proxy-free Claude Code routing for OpenRouter-hosted Anthropic models
  through OpenRouter's native Messages endpoint. Non-Anthropic OpenRouter
  models retain the compatibility proxy.

Fixed

• The experimental OpenAI OAuth transport now conforms to the ChatGPT Codex
  endpoint's required streaming-only, non-stored request format and rebuilds
  complete Responses output from SSE events. Live Claude Code verification
  passed with the Read, Write and Bash tools on the active OpenAI account.
• Extended live OpenAI verification to Edit, Glob, Grep, WebSearch, WebFetch,
  NotebookEdit, image reads, multi-call tool responses and a local MCP echo
  server. Agent subcalls return correct results but can continue scheduling
  calls instead of terminating; TodoWrite is unavailable in Claude Code
  2.1.211 and is not advertised as supported.
• Repeated the instrumented Claude/OpenAI tool matrix for gpt-5.5,
  gpt-5.4, gpt-5.4-mini and gpt-5.3-codex-spark. Every model passed
  Read, Write, Edit, Glob, Grep, Bash, WebSearch, WebFetch, NotebookEdit,
  image reads, a local MCP echo call and a bounded single Agent subcall.
• Tested the current OpenRouter flagships through Claude Code:
  deepseek/deepseek-v4-pro, z-ai/glm-5.2 and qwen/qwen3.7-max passed the
  full built-in tool matrix, MCP and Agent. moonshotai/kimi-k3 passed text,
  Read, Write, Edit, Glob, Bash, web, image reads and Agent, but Grep,
  NotebookEdit and MCP timed out amid repeated upstream failures.
• Verified moonshotai/kimi-k2.7-code as the more reliable Kimi fallback: it
  passed the complete built-in tool matrix, image reads, MCP and Agent in the
  same Claude Code/OpenRouter test setup where Kimi K3 remained partial.
• Retried the complete Kimi K3 matrix from a clean Claude configuration; the
  run reached Read but OpenRouter rate-limited the continuation with HTTP 429
  after roughly 290 seconds. The retry is recorded as inconclusive rather than
  as a new tool-compatibility failure.
• Verified anthropic/claude-sonnet-5 directly from Claude Code to OpenRouter
  with the local proxy stopped. Read, Write, Edit, Glob, Grep, Bash, web,
  NotebookEdit, image reads, MCP and Agent all passed through OpenRouter's
  Anthropic Messages endpoint.
• Verified Claude Code end to end against Azure OpenAI gpt-5.6-sol: text,
  Read, Write, Edit, Glob, Grep, Bash, WebSearch, WebFetch, NotebookEdit, image
  reads, multi-tool tasks, a local MCP echo tool and a bounded Agent subcall
  all passed through the unified proxy.
• Codex now connects directly to Azure OpenAI Responses v1 instead of routing
  through the local proxy. A command-backed vault helper supplies auth and a
  local Codex catalog prevents incompatible Azure /models refreshes. Live
  direct verification passed shell, file patching, web search and MCP tools.
• Commander no longer starts the compatibility proxy during catalog loading;
  proxy-backed clients start it on demand immediately before launch.
• Claude health probes and disconnected streaming clients are now handled
  without HTTP 501 responses or BrokenPipe tracebacks.
• Claude compatibility routes now use only the configured apiKeyHelper for
  loopback authentication, avoiding Claude Code's conflicting-auth warning
  when ANTHROPIC_AUTH_TOKEN and apiKeyHelper were both configured.
• Installation now stops a detached proxy launched through the installed
  symlink and preserves/replaces a legacy per-user launcher that would shadow
  the current checkout on PATH.
• Claude launches now resolve npm's installed platform-native executable when
  the generated claude symlink points at the non-executable fallback script.
